It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The embodiment of the application provides an elevator door system, including sill 2 and with sill sliding fit's elevator door plant 1, install elevator door plant slider in elevator door plant bottom.

As shown in fig. 1, the elevator door panel 1 slides on the sill 1 via the elevator door panel slider, and the opening and closing of the elevator door are completed.

In another embodiment, the elevator door panel 1 is formed by bending a plate material, the plate material is rolled back upwards at the bottom of the elevator door panel to form a standing part 11, and the bayonet 12 is arranged on the top side of the standing part 11. The bayonet 12 is used for installing an elevator door panel sliding block matched with the sill 2.

An embodiment of the application provides an elevator door plant slider, including being used for installing to the support 3 of elevator door plant bottom and being fixed in the support bottom and be used for with sill matched with guide block 4.

The support 3 comprises a bent support plate 31 and a hook 32 connected to the top edge of the support plate, and the guide block 4 is fixed to the bottom edge of the support plate 31;

the bottom of the elevator door panel is provided with a bayonet 12, the support plate 31 is arranged on one side of the bayonet 12, the hook 32 penetrates through the bayonet 12 and is bent downwards to form a downward hanging part 33, and the width of at least one part of the downward hanging part 33 is larger than that of the bayonet 12.

As shown in fig. 3 and 4, the guide block 4 of the door panel slider of the elevator is placed in the sill, and the hook 32 on the support plate 31 is engaged with the bayonet 12 with the upward opening, and in this application, unless otherwise specified, the description of the orientation, such as up, down, top, and bottom, can refer to fig. 3.

The bending of the support plate 31 itself is mainly to avoid the space interference during installation and use, and the specific bending form can be set according to the structure of the bottom of the elevator door panel, and also refer to the related prior art, and the shape is not the focus of the improvement of the present application.

In a use state, the support plate 31 and the drooping portion 33 are respectively positioned at two sides of the bayonet 12 in the horizontal direction, the support plate 31 and the drooping portion 33 are clamped at the position of the bayonet 12, namely, the elevator door panel sliding block can be fixed on an elevator door panel, and the bayonet is relatively long and narrow relative to the support plate 31, so that the support plate 31 cannot directly pass through the bayonet 12 in the horizontal direction. For the convenience of processing, the drooping part 33 generally adopts a flat strip structure, and in order to enable the supporting plate 31 and the drooping part 33 to be stably positioned at two sides of the bayonet 12, at least one part of the drooping part 33 has a width larger than that of the bayonet 12, so that the elevator door panel sliding block is effectively prevented from being separated from the bayonet 12 along the horizontal direction.

In another embodiment, as shown in fig. 2, the supporting plate 31 and the hook 32 are of a unitary structure. Usable panel integrated into one piece to can guarantee joint strength between the two, with the tired hidden danger that the adaptation elevator door plant long-term motion brought, in addition, the loaded down with trivial details of installation has also been avoided to integrative structure.

In order to keep the stability of elevator door plant slider position, prevent that sill 2 from scraping elevator door plant slider makes its skew or dislocation, in another embodiment, couple 32 is 2 ~ 4 of arranging side by side. The plurality of hooks are beneficial to improving the clamping strength with the elevator door panel, and in a further preferred embodiment, the hooks are arranged at equal intervals to reasonably distribute stress.

In another embodiment, the two opposite sides of the hanging part 33 extend oppositely, and the width of the extended hanging part is larger than that of the bayonet 12. Referring to fig. 5, the two opposite sides of the hanging-down portion 33 extend oppositely to form protruding wings 331, and each protruding wing 331 is respectively attached to the standing portion 11, so as to effectively prevent the elevator door panel sliding block from coming off the bayonet 12.

In this embodiment, the shape and position of each of the convex wings 331 are symmetrically distributed, and in other embodiments, each of the convex wings 331 may also be asymmetrically distributed, for example, the shape of the convex wings and the shape of the convex wings are different, and/or the height position of the convex wings distributed relative to the hanging-down portion 33 is different.

In another embodiment, the hanging-down part 33 is provided with a limiting part 332 protruding towards the support plate, and the limiting part 332 is used for abutting against the bottom wall of the bayonet 12.

The larger the contact area of the support plate 31 and the vertical part 11 is, the more the stability of the elevator door panel sliding block is facilitated, so that for the bayonet 12, the connection position of the support plate 31 and the downward hanging part 33 is higher, and a sufficient area expansion space is reserved for the support plate 31, and meanwhile, the limiting part 332 is arranged in the embodiment and is abutted against the bottom wall of the bayonet 12 to prevent the connection position of the support plate 31 and the downward hanging part 33 from sliding into the bayonet 12.

In another embodiment, the position-limiting portion 332 abuts against the supporting plate 31. As shown in fig. 7, the stopper 332 is sized to pass through at least the bayonet 12 and abut against the support plate 31, and the protruding wing 331 is further configured to clamp the standing portion 11 against the support plate 31.

In another embodiment, the hanging-down portion 33 is formed to detour toward the support plate 31 to form the stopper portion 332. As shown in fig. 6, the stopper 332 has a horizontal chevron shape and abuts against the bottom wall of the bayonet 12.

In another embodiment, the bottom edge 333 of the hanging-down part extends to the bottom surface of the elevator door panel 1 and wraps the bottom edge of the elevator door panel. Effectively improve the fixed strength between slider and the door plant, prevent that the slider rebound from deviating from the door plant bayonet socket.

The application provides an elevator door plant slider can install and change in different lift-cabin door systems in a flexible way, convenient, swiftly, reduce time cost effectively.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
